The Law of Non-Contradiction -- that no contradiction can be true -- has been a seemingly unassailable dogma since the work of Aristotle, in Book G of the Metaphysics. It is an assumption challenged from a variety of angles in this collection of original papers. Twenty-three of the world's leading experts investigate the "law," considering arguments for and against it and discussing methodological issues that arise whenever we question the legitimacy of logical principles. The result is a balanced inquiry into a venerable principle of logic, one that raises questions at the very...

The Law of Non-Contradiction has been high orthodoxy in Western philosophy since Aristotle. The so-called Law has been the subject of radical challenge in recent years by dialetheism, the view that some contradictions are indeed true. Many philosophers have taken the Law to be central to many of our most important philosophical concepts. In Doubt Truth to be a Liar, Graham Priest mounts the case against this. Starting with an analysis of Aristotle on the Law, he discusses the nature of truth, or rationality, or negation, and of logic itself, and argues that the Law is inessential to all of...

This second and extended edition of Priest's classic includes new chapters on Heidegger and Nagarjuna, as well as reflections on reactions to the first edition.

In Contradiction advocates and defends the view that there are true contradictions (dialetheism), a view that flies in the face of orthodoxy in Western philosophy since Aristotle. The book has been at the center of the controversies surrounding dialetheism ever since its first publication in 1987. This second edition of the book substantially expands upon the original in various ways, and also contains the author's reflections on developments over the last two decades. Further aspects of dialetheism are discussed in the companion volume, Doubt Truth to be a Liar, also published by Oxford...

This is the first substantial academic book to lay out the philosophical terrain within the study of the martial arts and to explore the significance of this fascinating subject for contemporary philosophy.

The book is divided into three sections. The first section concerns what philosophical reflection can teach us about the martial arts, and especially the nature and value of its practice. The second section deals with the other direction of the dialectical interplay between philosophy and the martial arts: how the martial arts can inform philosophical issues important in their...
